Answer / juggernaut
Master: Source with less number of records
Detail: Source with more number of records
For performance tuning: Joiner cache is created to store the data at the run time for Master port.
Join transformation is implemented based on the type of join we choose from the properties tab, using the options in the join type drop down list
1.Normal join: only matches record from both the tables
2.Master outer: All the records from Master table and only matches records from Detail
3.Detail outer: All the records from Detail and only matched records from Master
4.Full outer: Produces set of all records from Master and Detail
